While I don't entirely disagree with you, this highlights a major issue. To me, the 6 ranks fo AD all have distinct differences and give a very different feel to the different troops. I play Ariadna, and I would kill for an AD troop besides Mirage 5. I also balance the threat of Van Zant with the price discount of other Parachutists. I bring this up, not to debate the specifics of AD, but to point out that one person's irrelevant detail is another person's fundamental difference. There is likely room within the CC skills and weapons for some streamlining, but the fact that so many rules/weapons are used across factions makes it a bit different. I've said before, in many games, the Core Rules are tiny and the faction-specific rules are gargantuan. In Infinity, the Core Rules are deep and the faction rules are minuscule. This is why I don't envy CB moving into N4. I think they will make an awesome game and I've had a blast playing N3. I have never encountered a situation my opponent and I couldn't figure out and the community is the best out of any game. If CB keeps up what they've been doing, I think it will be outstanding.
